Is the translation cached?

If the translation is not cached, reinspection of A results in correctly
showing C, right? 

At least in the Slime Inspector, objects are reinspected on navigating
back from an inner object. I.e. in your example above: you'd start with
A, would go down to B, and when going back to A, A is reinspected and
hence will now show C instead of B.
